Detailed Implementation

[0041] This application provides a battery pack mounting bracket and a vehicle. The protective bracket can provide high structural strength for the water inlet and outlet area on the front side of the liquid cooling plate, preventing deformation or leakage due to vehicle scraping or falling impacts, which helps to ensure the overall safety performance of the battery pack.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please see Figures 1 to 4 The battery pack mounting bracket provided in this application mainly includes a front crossbeam 11, a liquid cooling plate 10, inlet and outlet water pipes 14, and a protective bracket 13. The liquid cooling plate 10 includes a first plate area 101 and a second plate area 102. The connecting area of ​​the first plate area 101 is located at the bottom of the front crossbeam 11 and connected to it. The main body area of ​​the first plate area 101 is located behind the connecting area and is used to support the battery module and cool it. The second plate area 102 is located at the top of the first plate area 101. The second plate area 102 protrudes forward relative to the bottom of the front crossbeam 11, and is connected to the front side of the connecting area 102. The inlet and outlet water pipe 14 is located on the front side of the front crossbeam 11 and above the second plate area 102, and the inlet and outlet water pipe 14 is connected to the internal flow channel of the second plate area 102. The protective bracket 13 is a high-strength bracket, connected to the top surface of the second plate area 102 and / or the front side of the front crossbeam 11, and at least part of the protective bracket 13 protrudes forward relative to the front side of the second plate area 102.

[0044] In this battery pack mounting bracket, since at least part of the protective bracket 13 is located in the second plate area 102 on the front side of the liquid cooling plate 10 and near the inlet / outlet water pipes 14, and protrudes forward relative to the second plate area 102, when the vehicle is moving forward, if the bottom of the vehicle is scraped or hit, such as scraping the bottom or falling, the obstacle under the vehicle will first contact the protective bracket 13. Thus, the protective bracket 13 can protect the second plate area 102 of the liquid cooling plate 10 and the inlet / outlet water pipes 14, avoiding the risk of deformation or damage to the second plate area 102 of the liquid cooling plate 10 and the inlet / outlet water pipes 14 during vehicle operation, which may lead to leakage and failure. This helps to improve the safety requirements of the inlet / outlet area on the front side of the battery pack mounting bracket under the extreme operating conditions of the vehicle.

[0045] In practical implementation, in the direction perpendicular to the outer side of the front crossbeam 11, the protruding length of the protective bracket 13 can be greater than or equal to the protruding length of the inlet / outlet water pipe fitting 14. Alternatively, the protruding length of the protective bracket 13 can be slightly less than the protruding length of the inlet / outlet water pipe fitting 14, which can also achieve a good protective effect. In practical implementation, the liquid cooling plate 10 and the inlet / outlet water pipe fitting 14 can be connected together by crimping through the protective bracket 13, which can improve the structural strength of the inlet / outlet water pipe fitting 14.

[0046] Please see Figure 2 In some embodiments, the inlet / outlet water pipe fitting 14 includes a first water pipe connector 141 and a second water pipe connector 142 arranged side-by-side along the length direction Y of the front crossbeam 11; and / or, the protective bracket 13 includes a plurality of bracket units 13' arranged side-by-side along the length direction Y of the front crossbeam 11, each bracket unit 13' being located in front of the front crossbeam 11 and connected to the front side surface of the front crossbeam 11. Specifically, the plurality of bracket units 13' includes a first bracket unit, a second bracket unit, and a third bracket unit arranged side-by-side and spaced apart along the length direction Y of the front crossbeam 11, wherein: the first bracket unit and the third bracket unit are located on both sides of the inlet / outlet water pipe fitting 14, respectively; the second bracket unit is located between the first water pipe connector 141 and the second water pipe connector 142. Thus, by arranging the plurality of bracket units 13' and the water pipe connectors at intervals, the sides and the entire inlet / outlet water pipe fitting 14 can be protected.

[0047] In some embodiments, the first water pipe connector 141 and the second water pipe connector 142 are two water pipe connectors arranged side by side and having the same or similar structures. Each water pipe structure includes a first connecting pipe 1401, an intermediate connecting member 1402, and a second connecting pipe 1403 connected in sequence. Specifically: the intermediate connecting member 1402 is connected to the front side of the front crossbeam 11; the first connecting pipe 1401 is connected to the front port of the intermediate connecting member 1402; and the second connecting pipe 1403 is connected to the lower port of the intermediate connecting member 1402 and is connected to the second plate area 102. Correspondingly, the first support unit, the second support unit, and the third support unit in the protective bracket 13 are all located below the first connecting pipe 1401 and are arranged at intervals along the length Y direction of the front crossbeam 11 with respect to the two second water pipe connectors 142.

[0048] Please see Figures 5 to 16In some embodiments, at least a portion of the support unit 13' is provided with a plurality of first through holes 130, which are arranged sequentially along the front-rear direction X of the support unit 13' and penetrate through both sides of the support unit 13' along the length direction Y of the front crossbeam 11; and / or, at least a portion of the support unit 13' is provided with second through holes 131 on its top and / or bottom surfaces. Thus, through the first through holes 130 and / or second through holes 131 provided in the support unit 13', the support unit 13' can provide both support and protection, as well as a certain degree of buffering capacity.

[0049] In some embodiments, the second through hole 131 is located in the front end region of the top and / or bottom surface of the support unit 13'; and / or, in a direction perpendicular to the plane of the liquid cooling plate 10, the front end thickness of the support unit 13' is smaller than the rear end thickness of the support unit 13' (see [reference]). Figure 5 and Figure 8 Thus, the collapse force of each support unit 13' gradually increases during the buffering process, which can simultaneously play a good supporting and protective role and a buffering effect.

[0050] Please see Figures 11 to 16 In some embodiments, the rear sides of adjacent support units 13' are connected by a connecting plate 132, which facilitates the installation, disassembly and maintenance of the protective support 13 and helps to ensure that multiple support units 13' maintain a uniform installation height.

[0051] In some embodiments, each support unit 13' is a casting or injection molded part, in which case the opening cross-section of the first through hole 130 is triangular, rectangular, trapezoidal, circular, or elliptical. In some embodiments, each support unit 13' is a sheet metal structural component. In this case, the hollow structure of the sheet metal structural component forms the first through holes 130 arranged side by side, wherein at least a portion of the first through holes 130 are provided with inclined or cross-arranged reinforcing ribs 133.

[0052] For example, see Figures 5 to 7 In some embodiments, the protective bracket 13 adopts a multi-cavity structure. This structure forms a high-strength bracket structure by using a rectangular cavity, two isosceles triangular cavities, one scalene triangular cavity, and one equilateral triangular cavity. The rectangular cavity is located at the front end of the protective bracket 13, and the rectangular cavity forms a Z-direction height difference with an adjacent isosceles triangular cavity on its rear side. Thus, the rectangular cavity can appropriately absorb deformation and play a buffering and protective role for the battery pack mounting bracket.

[0053] For example, see Figures 8 to 10In some embodiments, the protective bracket 13 adopts a three-cavity structure. This structure forms a high-strength bracket structure by using rectangular cavities, right-angled triangles, and polygonal cavities (some of whose interior angles are right angles). The rectangular cavity is located at the front end of the protective bracket 13, and the rectangular cavity forms a Z-direction height difference with the right-angled triangle cavity adjacent to its rear side. Thus, the rectangular cavity can appropriately absorb deformation and play a buffering and protective role for the battery pack mounting bracket.

[0054] For example, see Figures 11 to 13 In some embodiments, the protective bracket 13 adopts a rectangular cavity structure. This structure uses three or more rectangular cavities, which can be different or the same, with only some of the rectangular cavities being the same. Its main function is to protect the inlet and outlet water pipes 14 through the energy absorption deformation of the three or more rectangular cavities. At the same time, the integrated connecting plate 132 serves as the rear side plate of multiple support units 13' in the protective bracket 13, forming multiple support units 13' into a whole, and is connected to the front crossbeam 11 by welding.

[0055] For example, see Figure 14 In some embodiments, the protective bracket 13 adopts a rectangular cavity with diagonal ribs. This structure uses multiple rectangular cavities, and except for the rectangular cavity located at the frontmost side, each of the remaining rectangular cavities is reinforced with diagonal ribs (i.e., Figure 11 The reinforcing rib 133 divides the rectangular cavity into two triangular cavity structures, and this combined structure can improve the structural strength of the support unit 13'. The use of diagonal ribs enhances the structural stability and high stiffness of the entire support structure of the support unit 13'.

[0056] For example, see Figure 15 In some embodiments, the protective bracket 13 adopts a rectangular cavity anti-dip rib structure. This structure uses multiple rectangular cavities. Except for the rectangular cavity located at the frontmost side, each of the remaining rectangular cavities is reinforced with anti-dip ribs (i.e., Figure 11 The reinforcing rib 133 divides the rectangular cavity into two triangular cavity structures, and this combined structure can improve the structural strength of the support unit 13'. The use of anti-diagonal ribs enhances the structural stability and high stiffness performance of the support unit 13' and even the entire support.

[0057] Please see Figure 16 In some embodiments, the protective bracket 13 adopts a rectangular cavity cross-rib structure. This structure uses multiple rectangular cavities. Except for the rectangular cavity located at the frontmost side, each of the remaining rectangular cavities is divided into four triangular cavity structures by cross-arranged ribs. This combined structure can improve the structural strength of the bracket unit 13'. The purpose of using cross-ribs is to improve the structural stability and high rigidity performance of the bracket unit 13' and even the entire bracket.

[0058] In practice, the protective bracket 13 and the second plate area 102 can be fixedly connected by adhesive; and / or, the protective bracket 13 and the front side of the front crossbeam 11 can be welded together to form a whole.

[0059] As can be seen, in the battery pack mounting bracket provided in this application embodiment, the protective bracket 13 can support and protect the water inlet and outlet areas of the liquid cooling plate 10 connected to its bottom, improve the structural rigidity at this position, and effectively avoid problems such as deformation or leakage in the water inlet and outlet areas of the liquid cooling plate 10.

[0060] Further, please see Figures 1 to 3 In this battery pack mounting bracket, along the length Y direction of the front crossbeam 11, ear plates 12 are respectively provided on both sides of the protective bracket 13. The ear plates 12 are connected to the front side of the front crossbeam 11, and a gap greater than zero is provided between the ear plates 12 and the protective bracket 13. The ear plates 12 allow the battery pack mounting bracket to connect to the vehicle body. Furthermore, in some embodiments, the front crossbeam 11 is a hollow structure to reduce vehicle weight; in other embodiments, the bottom of the front crossbeam 11 is provided with a downwardly extending extension plate 15 to protect the liquid cooling plate 10 and to improve the structural rigidity and deformation resistance of the front crossbeam 11.

[0061] In some embodiments, an annular frame is provided above the liquid cooling plate 10, and the aforementioned front crossbeam 11 is the front side crossbeam of this annular frame. Additionally, please refer to... Figure 17 The annular frame also includes a rear crossbeam assembly 17 located behind the battery module, and longitudinal beams 16 located on both sides of the battery module. Thus, the annular frame can be fitted around the periphery of the battery module to provide accommodating space for it.

[0062] This application also provides a vehicle, including a vehicle body and a battery module, as well as the battery pack mounting bracket described above. The battery module is located behind the front crossbeam 11 in the battery pack mounting bracket, and above the main body area of ​​the first plate area 101 of the liquid cooling plate 10 in the battery pack mounting bracket. The battery module is mounted to the vehicle body via the battery pack mounting bracket. When the front crossbeam 11 is a side crossbeam in an annular frame above the liquid cooling plate 10, the battery module is located within the annular frame in the battery pack mounting bracket, and above the main body area of ​​the first plate area 101 of the liquid cooling plate 10 in the battery pack mounting bracket. In specific implementations, the battery module can be a blade module. Experiments have shown that the battery pack mounting bracket has good overall rigidity. While meeting the overall battery pack assembly function, it can improve the vehicle's drop impact performance. Its structure is compact, rigid, and relatively lightweight. More importantly, it improves the safety requirements of the vehicle under extreme operating conditions in the water inlet / outlet area of ​​the liquid cooling plate near the battery pack, demonstrating strong practicality.

[0063] It should be noted that the term "front" in this application is based on the vehicle's direction of travel. For example, the direction from the rear to the front of the vehicle is the front, and the direction from the front to the rear of the vehicle is the rear. For any component in the battery pack mounting bracket, the side of the component closer to the front of the vehicle is the front side, and the side of the component closer to the rear of the vehicle is the rear side.

[0064] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed.

[0065] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0066] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
