Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a battery pack connection bracket and a vehicle. Background Technology

[0002] In new energy vehicles, the battery pack is a core component, and the reliability of its connection to the vehicle frame directly affects the vehicle's safety and lifespan. In related technologies, the battery pack is typically connected to the frame via multiple brackets. However, since the brackets are usually connected to the battery pack first—meaning the battery pack connection bolts are first installed on the brackets and the battery pack—and then connected to the frame, the limited space in the bracket installation area can easily lead to interference between the installation tools and the battery pack connection bolts when connecting the brackets to the frame and brackets. In this situation, the installation tools cannot reach into the brackets to tighten the battery pack connection bolts, resulting in an unsecured connection between the brackets and the frame. This can easily lead to the battery pack (especially large-capacity battery packs) detaching when the battery pack is too heavy. Utility Model Content

[0003] The purpose of this disclosure is to provide a battery pack connection bracket and a vehicle to reduce interference with installation tools and improve the connection strength between the vehicle frame and the battery pack.

[0004] To achieve the above objectives, this disclosure provides a battery pack connection bracket, comprising: A support base, wherein two ends of the support base are respectively formed with oppositely arranged mounting seats; Two first mounting holes are arranged on the mounting base at one end of the support base; Two second mounting holes are arranged on a mounting base at the other end of the support base, wherein the two first mounting holes are spaced apart along a first direction, and the two second mounting holes are spaced apart along the first direction; the mounting base is formed at both ends of the support base in a second direction, the second direction being perpendicular to the first direction; and A mounting slot is provided for the movement of the installation tool. The mounting slot is formed on the support base and is located between the first mounting hole and the second mounting hole.

[0005] Optionally, the second mounting hole is offset from the first mounting hole in the first direction to form the mounting groove between the first mounting hole and the second mounting hole, wherein the mounting groove is recessed toward the middle region of the support in the first direction.

[0006] Optionally, in the first direction, the central axis of the two second mounting holes is located between the central axis of the two first mounting holes.

[0007] Optionally, the mounting base includes: Two first mounting seats are arranged at intervals along the first direction, and each first mounting seat is arranged in a one-to-one correspondence with the first mounting hole. A second mounting base is spaced apart from the first mounting base in the second direction, and second mounting holes are spaced apart on the second mounting base; and A third mounting base is disposed between two first mounting bases in the first direction. The third mounting base is provided with a third mounting hole. The second mounting base is also provided with a fourth mounting hole, which is disposed between two second mounting holes and is disposed opposite to the third mounting hole in the second direction.

[0008] Optionally, the support base is further provided with a first through hole, which is located between the third mounting hole and the fourth mounting hole, and communicates with the third mounting hole and the fourth mounting hole. The first through hole is configured to allow an installation tool to be inserted.

[0009] Optionally, the support base includes a connecting plate, which is connected to the edges of the first mounting base, the second mounting base, and the third mounting base in a third direction. The first through hole is formed in the middle region of the connecting plate, and the mounting groove is formed at the edge of the connecting plate in a first direction, wherein the third direction is perpendicular to the first direction and the second direction, respectively.

[0010] Optionally, the support base further includes two connecting ribs spaced apart in the first direction. The connecting ribs are disposed on the connecting plate. Each connecting rib includes a main segment and a branch segment. The main segment is connected between the first mounting base and the second mounting base, and the branch segment is connected between the main segment and the third mounting base. In the third direction, the projections of the main segment and the branch segment are both located on the connecting plate.

[0011] Optionally, a reinforcing plate is further provided between the main section and the branch section, and in the first direction, the reinforcing plate is located between the first mounting base and the third mounting base.

[0012] According to another aspect of this disclosure, a vehicle is provided, comprising: The frame includes mounting beams extending in a first direction; The battery pack is located below the vehicle frame; and The aforementioned battery pack connecting bracket has one end connected to the bottom of the mounting beam and the other end connected to the battery pack.

[0013] Optionally, there are multiple battery pack connecting brackets, and the multiple battery pack connecting brackets are spaced apart along the first direction.

[0014] The above technical solution involves creating a mounting groove between the first and second mounting holes, allowing the installation tool to extend and move within it. After the battery pack fasteners are engaged with the second mounting hole, the installation tool can move within sufficient space in the mounting groove, thereby installing the frame fasteners without interfering with the battery pack fasteners. This effectively tightens the frame fasteners, improves the connection between the battery pack connecting bracket and the frame, and enhances the overall vehicle connection rigidity.

Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined in relation to the actual orientation of the vehicle during use, while directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not imply sequentiality or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0026] According to one embodiment of this disclosure, such as Figures 1 to 4 As shown, a battery pack connection bracket is provided, which may include a support base with mounting seats formed at both ends of the support base. Two first mounting holes 31 may be arranged on the mounting seat at one end of the support base, and the first mounting holes 31 may mate with a vehicle frame fastener 5. Two second mounting holes 32 may be arranged on the mounting seat at the other end of the support base, and the second mounting holes 32 may mate with a battery pack fastener 6. The two first mounting holes 31 are spaced apart along a first direction, and the two second mounting holes 32 are spaced apart along the first direction. The mounting seats are formed at both ends of the support base in a second direction, which is perpendicular to the first direction. The support base also has a mounting groove 30, which allows an installation tool 7 to move, and the mounting groove 30 is located between the first mounting holes 31 and the second mounting holes 32.

[0027] It should be noted that when the battery pack connecting bracket is connected to the frame 1 and the battery pack 2, the second direction here can also refer to the height direction. In the second direction, the mounting groove 30 can be formed between the first mounting hole 31 and the second mounting hole 32, so that the installation tool 7 for installing the frame fastener 5 can be inserted and moved, thereby avoiding obstruction of the installation tool 7 for installing the frame fastener 5. Figure 1 There are two installation tools 7. The upper installation tool 7 is used to install the frame fastener 5, and the lower installation tool 7 is used to install the battery pack fastener 6.

[0028] Through the above technical solution, an installation groove 30 is opened between the first mounting hole 31 and the second mounting hole 32, allowing the installation tool 7 to extend and move. After the battery pack fastener 6 is engaged with the second mounting hole 32, the installation tool 7 can move through the sufficient space opened in the installation groove 30, thereby installing the frame fastener 5 without interfering with the battery pack fastener 6, effectively tightening the frame fastener 5, improving the connection effect between the battery pack connecting bracket and the frame 1, and improving the overall vehicle connection rigidity.

[0029] Here, the mounting slot 30 may also be made larger in size so as to simultaneously accommodate the installation tool 7 for mounting the frame fastener 5 and the installation tool 7 for mounting the battery pack fastener 6. This disclosure does not limit this.

[0030] The first mounting hole 31 and the second mounting hole 32 can be arranged opposite each other, so that the mounting groove 30 can be formed as an arc with a large space. This ensures that after the battery pack fastener 6 is installed, there is sufficient space on both sides of the first mounting hole 31 and the second mounting hole 32 in the first direction, allowing the installation tool 7 to extend from the side to install the frame fastener 5. Alternatively, the second mounting hole 32 and the first mounting hole 31 can be staggered in the first direction, forming the mounting groove 30 between the first mounting hole 31 and the second mounting hole 32. Specifically, in the first direction, the mounting groove 30 can be recessed towards the middle area of ​​the support. The mounting groove 30 prevents interference between the installation tool 7 for installing the frame fastener 5 and the battery pack fastener 6 after installation.

[0031] Regarding the specific placement of the first mounting hole 31 and the second mounting hole 32, in the first direction, the central axis of the two second mounting holes 32 can be located between the central axes of the two first mounting holes 31. It should be noted that the central axis here refers to the central axis of the first mounting hole 31 and the second mounting hole 32 themselves. The central axis of each first mounting hole 31 or second mounting hole 32 extends along the second direction. In this way, the mounting groove 30 can be symmetrically arranged and located at the edge of the support base, thereby ensuring the strength of the battery pack connection bracket while avoiding the installation tool 7.

[0032] According to one embodiment of this disclosure, such as Figures 1 to 4 As shown, the battery pack connection bracket may further include two first mounting seats 301, a second mounting seat 302, and a third mounting seat 303. The two first mounting seats 301 may be spaced apart along a first direction, with each first mounting seat 301 corresponding to a first mounting hole 31. The second mounting seat 302 may be spaced apart from the first mounting seats 301 in a second direction, and second mounting holes 32 may be spaced apart on the second mounting seat 302. The third mounting seat 303 may be positioned between the two first mounting seats 301 in the first direction, and a third mounting hole 33 may be provided on the third mounting seat 303. The second mounting seat 302 may also have a fourth mounting hole 34 positioned between the two second mounting holes 32, and the fourth mounting hole 34 and the third mounting hole 33 may be positioned opposite each other in the second direction.

[0033] Here, the third mounting hole 33 can be selectively engaged with the frame fastener 5. That is, the third mounting hole 33 can be selectively engaged with the frame fastener 5 to enhance the stability of the connection between the battery pack connecting bracket and the frame 1. Alternatively, the third mounting hole 33 can be left empty, i.e., the frame fastener 5 is not installed. This disclosure does not limit this.

[0034] Similarly, in the first direction, the fourth mounting hole 34 can be positioned between the two second mounting holes 32. The fourth mounting hole 34 can selectively engage with the battery pack fastener 6. The fourth mounting hole 34 and the third mounting hole 33 are spaced apart in the second direction. That is, the fourth mounting hole 34 can be selectively engaged with the battery pack fastener 6 to enhance the stability of the connection between the battery pack connecting bracket and the vehicle frame 1. Alternatively, the fourth mounting hole 34 can be left empty, i.e., without the battery pack fastener 6 installed. Or, since the battery pack connecting bracket is usually installed with the battery pack 2 first during installation, a positioning pin that engages with the battery pack 2 can also be installed at the fourth mounting hole 34 to enhance the installation effect with the battery pack 2. This disclosure does not limit this aspect.

[0035] Furthermore, such as Figures 1 to 4 As shown, the support base may also have a first through hole 35, which can be located between the third mounting hole 33 and the fourth mounting hole 34, and communicates with both the third mounting hole 33 and the fourth mounting hole 34. The first through hole 35 is configured to allow the installation tool 7 to extend into it. This achieves weight reduction for the battery pack connection bracket and also creates a clearance between the third mounting hole 33 and the fourth mounting hole 34 to allow the installation tool 7 to pass through the first through hole 35 when the third mounting hole 33 and the fourth mounting hole 34 need to mate with the corresponding frame fastener 5 or battery pack fastener 6.

[0036] Furthermore, such as Figures 1 to 4 As shown, the support base may include a connecting plate 304. In the third direction, the connecting plate 304 can be connected to the edges of the first mounting base 301, the second mounting base 302, and the third mounting base 303. A first through hole 35 is formed in the middle area of ​​the connecting plate 304, and a mounting groove 30 is formed at the edge of the connecting plate 304 in the first direction. The third direction is perpendicular to the first and second directions, respectively. The connecting plate 304 is connected to one side of the first mounting base 301, the second mounting base 302, and the third mounting base 301. This ensures the connection between the first mounting base 301, the third mounting base 303, and the second mounting base 302, and avoids filling the space between them with connecting material. This effectively reduces the amount of connecting material used between the first mounting base 301, the third mounting base 303, and the second mounting base 302, thereby reducing the overall weight of the battery pack connecting bracket.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the support may further include two connecting ribs 305 spaced apart in the first direction. The connecting ribs 305 are disposed on the connecting plate 304 and include a main segment 3051 and a branch segment 3052. The main segment 3051 connects the first mounting base 301 and the second mounting base 302, and the branch segment 3052 connects the main segment 3051 and the third mounting base 303. In the third direction, the projections of both the main segment 3051 and the branch segment 3052 can be located on the connecting plate 304. The function of the connecting ribs 305 is to enhance the connection strength between the first mounting base 301, the third mounting base 303, and the second mounting base 302. Here, the main segment 3051 and the branch segment 3052 can form a Y-shaped structure. The main segment 3051 and the branch segment 3052 can be straight ribs or curved ribs; this disclosure does not limit this.

[0038] Here, a reinforcing plate 3053 can also be provided between the main section 3051 and the support section 3052. In the first direction, the reinforcing plate 3053 is located between the first mounting base 301 and the third mounting base 303 to prevent excessive shear force from causing the connecting rib 305 to tear and resulting in displacement between the first mounting base 301 and the third mounting base 303, thereby strengthening the connection strength between the first mounting base 301 and the third mounting base 303 and the rigidity of the connecting rib 305.

[0039] Based on the above solutions, this disclosure also provides a vehicle, such as Figures 1 to 7As shown, the vehicle may include a frame 1, a battery pack 2, and the aforementioned battery pack connecting bracket. The frame 1 may include a mounting beam 11 extending along a first direction, and the battery pack 2 may be located below the frame 1. One end of the battery pack connecting bracket may be connected to the bottom of the mounting beam 11, and the other end of the battery pack connecting bracket may be connected to the battery pack 2. Here, there may be multiple battery pack connecting brackets, and these multiple battery pack connecting brackets may be spaced apart along the first direction, thereby improving the connection strength between the frame 1 and the battery pack 2.

[0040] Other brackets can also be connected between the frame 1 and the battery pack 2. Specifically, the aforementioned battery pack connecting bracket is a first bracket 3. One end of the first bracket 3 can be connected to the bottom of the mounting beam 11, and the other end of the first bracket 3 is connected to the battery pack 2. The vehicle may also include a second bracket 4, which is spaced apart from the first bracket 3 in a first direction. One end of the second bracket 4 is connected to the side of the mounting beam 11, and the other end of the second bracket 4 is connected to the battery pack 2. Here, the first direction can be the vehicle's direction of travel, and the third direction mentioned below can be the vehicle's width direction. Alternatively, the first direction can be the vehicle's width direction, and the third direction can be the vehicle's direction of travel; this disclosure does not limit this.

[0041] Specifically, the first bracket 3 and the second bracket 4 are connected to the mounting beam 11 of the frame 1 at different positions. This not only disperses the load on the battery pack 2 but also distributes the stress at the connection between the battery pack 2 and the frame 1, reducing stress concentration. This improves the installation strength between the frame 1 and the battery pack 2 while meeting the overall vehicle rigidity requirements. Furthermore, since the first bracket 3 is connected to the bottom of the mounting beam 11, it also saves installation space on the side of the mounting beam 11 corresponding to the first bracket 3, thereby improving the overall vehicle space utilization.

[0042] It should be noted that there can be two mounting beams 11, spaced apart along a third direction, and the two mounting beams 11 can be connected by a crossbeam. Regarding the mounting structure of the battery pack 2 with the first bracket 3 and the second bracket 4, the battery pack 2 can have two mounting edges 21 on both sides along a third direction, each corresponding to one of the mounting beams 11. The corresponding mounting beams 11 and mounting edges 21 can connect to the first bracket 3 and the second bracket 4. Alternatively, the battery pack 2 can have multiple lifting lugs on both sides of a third direction, with each first bracket 3 or second bracket 4 corresponding to one of the multiple lifting lugs; this disclosure does not limit this. Both the first bracket 3 and the second bracket 4 can be integrally formed, which improves the strength of the first bracket 3 and the second bracket 4, thereby improving the strength of the connection structure between the entire battery pack 2 and the vehicle frame 1.

[0043] Regarding the number of the first support 3 and the second support 4, here, as Figure 2As shown, there can be multiple first brackets 3, which are spaced apart along a first direction. There can be two second brackets 4, which can be located between the two second brackets 4 along the first direction. The number of first brackets 3 can be three or four, depending on the length of the frame 1, and this disclosure does not limit this. In this way, the multiple first brackets 3 spaced apart along the first direction can evenly distribute the stress generated by the connection between the battery pack 2 and the frame 1 from the bottom, ensuring force balance. The two second brackets 4 are located on both sides of the multiple first brackets 3. The second brackets 4 are connected to the side of the mounting beam 11 of the frame 1. The connection area of ​​the side connection is larger than that of the bottom connection. Although this is more conducive to stress dispersion and makes the connection strength between the second bracket 4 and the mounting beam 11 greater than that of the first bracket 3, the first bracket 3 is lighter than the second bracket 4. Therefore, distributing the second brackets 4 with higher connection strength at both ends of the connection structure and distributing the lighter first brackets 3 in the middle is beneficial for better stress dispersion and also meets the requirements of lightweight design of the connection structure.

[0044] According to one embodiment of this disclosure, such as Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, the second bracket 4 may include a first mounting plate 41 and a second mounting plate 42. The first mounting plate 41 may have a plurality of first connecting holes 411 spaced apart along a first direction, where the first connecting holes 411 can mate with the frame fasteners 5. The second mounting plate 42 may be connected to the edge of the first mounting plate 41, and the second mounting plate 42 and the first mounting plate 41 are arranged at an angle to each other. The second mounting plate 42 may have a plurality of second connecting holes 421 spaced apart along the first direction, and the second connecting holes 421 can also mate with the battery pack fasteners 6. Because there is an angle between the first mounting plate 41 and the second mounting plate 42, the hole orientations of the first connecting holes 411 and the second connecting holes 421 are different. Thus, when the second bracket 4 is connected to the frame 1, it can be connected to the side of the mounting beam 11 of the frame 1. Since the side of the mounting beam 11 has sufficient thickness and strength, when the second bracket 4 is connected to the side of the mounting beam 11, the connection strength between the second bracket 4 and the frame 1 can be effectively improved, thereby improving the rigidity of the entire vehicle.

[0045] Furthermore, since the side of the mounting beam 11 has sufficient height, multiple first connecting holes 411 can also be spaced out on the first mounting plate 41 in both the first and second directions, with the first direction perpendicular to the second direction. When the second bracket 4 is connected to the vehicle frame 1 and the battery pack 2, the second direction can also refer to the height direction. Here, the first mounting plate 41 can also have multiple rows of first connecting holes 411 in the height direction, which can effectively improve the connection strength between the second bracket 4 and the vehicle frame 1, thereby improving the overall rigidity of the vehicle.

[0046] Furthermore, such as Figures 5 to 7 As shown, the second bracket 4 may further include a first reinforcing rib 43 and a second reinforcing rib 44. In a third direction, the first reinforcing rib 43 is located on one side of the second bracket 4, and the second reinforcing rib 44 is located on the other side of the second bracket 4. When the second bracket 4 is connected to the frame 1, the first reinforcing rib 43 may be located on the side of the second bracket 4 away from the frame 1, and the second reinforcing rib 44 may be located on the side of the second bracket 4 closer to the frame 1. The projection of the first reinforcing rib 43 along a third direction and the projection of the second reinforcing rib 44 along a third direction are at least partially non-coincident. The third direction may be perpendicular to the first direction and the second direction, respectively. Here, the first reinforcing rib 43 and the second reinforcing rib 44 may be completely non-coincident or only partially non-coincident; this disclosure does not limit this. In this way, the first reinforcing rib 43 and the second reinforcing rib 44 are formed on different surfaces of the second bracket 4, and their extension directions are different, forming a staggered arrangement, thereby improving the overall strength of the second bracket 4.

[0047] Specifically, such as Figures 5 to 7 As shown, the first mounting plate 41 may further include a first segment 412 and a second segment 413 connected to each other. A first connecting hole 411 is disposed on the first segment 412, and the second segment 413 is connected to the second mounting plate 42. In the first direction, there may be two first reinforcing ribs 43 spaced apart. One end of each first reinforcing rib 43 is disposed on the first mounting plate 41 and located between two adjacent first connecting holes 411 along the first direction, while the other end extends towards the second mounting plate 42 and connects to a second connecting hole 421 at the edge. When the second bracket 4 is connected to the frame 1, the first segment 412 contacts the mounting beam 11 of the frame 1, and the second segment 413 is spaced apart from the mounting beam 11. Thus, the surface of the first reinforcing rib 43 does not contact the mounting beam 11. The first reinforcing rib 43 may be disposed on both the first segment 412 and the second segment 413 to ensure the strength of the second bracket 4 without affecting other structures. Here, the first segment 412 and the second segment 413 can be set at an angle to each other. In this way, when the second bracket 4 is connected to the frame 1, the other end of the second segment 413 can extend into the area between the frame 1 and the battery pack 2, thereby reducing the space occupied on the outside of the frame 1.

[0048] Furthermore, such as Figures 5 to 7 As shown, in the first direction, there can be two second reinforcing ribs 44 spaced apart. When the second bracket 4 is connected to the frame 1, since the second reinforcing ribs 44 are located on the side of the second bracket 4 closest to the mounting beam 11, the second reinforcing ribs 44 can be set on the second section 413. In this way, the first section 412 can fit against the side of the mounting beam 11, so as to reduce the space occupied by the second bracket 4 on the side of the mounting beam 11 while ensuring the strength of the second bracket 4. Here, one end of each second reinforcing rib 44 can be connected to the second mounting plate 42. When there are three second connecting holes 421, it can also be connected to the second connecting hole 421 in the middle area, and the other end extends to the connection between the first mounting plate 41 and the second mounting plate 42.

[0049] To reduce the weight of the second support 4, such as Figure 5 and Figure 6 As shown, at least one second through hole 45 may be provided on the first mounting plate 41, wherein the second through hole 45 may be located between two first reinforcing ribs 43 to reduce the weight of the first mounting plate 41. In the embodiment where the first mounting plate 41 includes a first segment 412 and a second segment 413, the first segment 412 and the second segment 413 may also be provided with second through holes 45 respectively, and this disclosure does not limit this. Here, the shape of the second through hole 45 may be circular or oblong, and this disclosure also does not limit this.

[0050] According to one embodiment of this disclosure, such as Figure 5 and Figure 6 As shown, the first mounting plate 41 may also have multiple grooves 414. The grooves 414 may be located at the edge of the first mounting plate 41 in at least one of the first direction and the second direction. That is, the grooves 414 may be located at the edge of the first mounting plate 41 in the first direction, at the edge of the first mounting plate 41 in the second direction, or at the edges in both directions. This disclosure does not limit this. In this way, the amount of material used in the first mounting plate 41 can be effectively reduced without affecting the connection between the second bracket 4 and the frame 1, thereby reducing the weight of the second bracket 4.

[0051] Furthermore, in the scheme where multiple first connecting holes 411 are spaced apart along a first direction and a second direction, a groove 414 can be formed between two adjacent first connecting holes 411 in at least one of the first direction and the second direction. In this way, the mounting point of the first mounting plate 41 and the frame 1 is located outside the groove 414, ensuring that the area for removing material from the first mounting plate 41 is located near the mounting point of the first mounting plate 41 and the frame 1. This reduces the overall weight of the second bracket 4 while ensuring the installation strength of the first mounting plate 41 and the frame 1.

[0052] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0054] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
