Detailed Implementation

[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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0044] A battery pack, also known as a battery array, is a power supply device that combines multiple individual battery cells in series, parallel, or a combination of series and parallel connections to meet the voltage, capacity, and power requirements of specific equipment or applications. Battery packs used in vehicles are typically mounted on both sides of the vehicle frame via a frame (at least part of the battery pack can be placed inside the corresponding frame). Since the vehicle frame is located at the bottom of the vehicle, mounting the battery pack on both sides of the frame allows the battery pack to be further away from the driver's cab, improving driver safety to some extent; it also reduces the difficulty of battery pack installation and replacement, and lowers the risk of battery pack hoisting; furthermore, placing the battery pack at the bottom of the vehicle does not encroach on the interior space of the passenger compartment, improving the utilization of passenger space. However, due to the continuous vibrations that occur during vehicle operation, and the fact that one side of the frame connects to one side of the vehicle frame, the connection area is relatively small and the number of connection points is limited, which may lead to loosening at the connection between the battery pack frame and the vehicle frame, reducing stability.

[0045] In view of this, embodiments of this application provide a battery pack frame to overcome at least one of the above-mentioned technical problems.

[0046] Please see Figure 1 and Figure 2 In this embodiment of the application, the battery pack frame is used to connect the vehicle frame beam 90, and the battery pack frame includes a first frame 10 and a second frame 20.

[0047] The first frame 10 includes a first body 11 and at least one first extension 12 connected to each other. At least a portion of the first body 11 is located on one side of the frame beam 90 along the first direction X and is connected to the frame beam 90. At least a portion of the first extension 12 is located on one side of the frame beam 90 in the second direction Y and is connected to the frame beam 90. The first direction X and the second direction Y intersect, preferably perpendicular to each other. The second frame 20 includes a second body 21 and at least one second extension 22 connected to each other. At least a portion of the second body 21 is located on the other side of the frame beam 90 along the first direction X and is connected to the frame beam 90. At least a portion of the second extension 22 is located on one side of the frame beam 90 in the second direction Y and is connected to the frame beam 90. The second extension 22 is connected to a corresponding first extension 12. (The first direction X is the width direction of the first body 11, the second direction Y is the height direction of the first body 11, and the third direction Z is the length direction of the first body 11).

[0048] It is understandable that a first frame 10 and a second frame 20 are respectively provided on both sides of the frame beam 90 along the first direction X. There can be multiple first frames 10, which can be arranged at intervals along the third direction Z and are all connected to the same side of the frame beam 90. There can also be multiple second frames 20, which correspond to the number and position of the first frames 10. Multiple second frames 20 can be arranged at intervals along the third direction Z and are all connected to the same side of the frame beam 90.

[0049] The first frame 10 includes a first body 11 and at least one first extension 12. The first body 11 may be formed by welding together multiple high-strength steel pipes to form a frame structure. The first extension 12 and the first body 11 may be an integral structure. A receiving cavity 70 may be formed on the first body 11, into which at least a portion of the battery pack can be placed, thereby mounting the battery pack onto the vehicle frame beam 90 via the first frame 10. The first extension 12 may be formed by extending a steel pipe from the first body 11, and the first extension 12 is located at the top or bottom of the vehicle frame beam 90 (i.e., on one side of the vehicle frame beam 90 in the second direction Y), and is fixedly connected to the vehicle frame beam 90, such as by welding or bolting. The first extension 12 connects the first body 11 to the bottom or top of the frame beam 90, increasing the connection points between them and further improving the strength and stability of the connection. This prevents the first body 11 from loosening due to vibration, ensuring the stability of the battery pack installed within it. Similarly, the second frame 20 on the other side of the frame beam 90 includes a second body 21 and a second extension 22. The second body 21 can be welded from multiple high-strength steel pipes to form a frame structure, and the second extension 22 and the second body 21 can be an integral structure. A receiving cavity 70 can also be formed on the second body 21 to hold the battery pack, thereby mounting the battery pack onto the frame beam 90 via the second frame 20. The second extension 22 can also be formed by extending a steel pipe from the second body 21, and the second extension 22 is also located at the top or bottom of the frame beam 90 (i.e., on one side of the frame beam 90 in the second direction Y), and is fixedly connected to the frame beam 90, such as by welding or bolting. By connecting the second body 21 to the bottom or top of the frame beam 90 through the second extension 22, the connection points between the second body 21 and the frame beam 90 are increased, which can further improve the firmness and stability of the connection between the two, prevent the second body 21 connected to the frame beam 90 from loosening due to vibration, and ensure the stability of the battery pack installed in the second body 21.

[0050] The first extension 12 and the second extension 22 can be multiple. The first body 11, in addition to being connected to the frame beam 90 on one side, is also connected to the bottom or top of the frame beam 90 via multiple first extensions 12. The second body 21, in addition to being connected to the frame beam 90 on one side, is also connected to the bottom or top of the frame beam 90 via multiple second extensions 22. This arrangement improves the stability of the connection between the first frame 10, the second frame 20, and the frame beam. Furthermore, the first extensions 12 and their corresponding second extensions 22 can also be connected. This connection further enhances the stability of both, thereby improving the stability of the corresponding first frame 10 and second frame 20 and preventing loosening due to vibration.

[0051] Please see Figure 2 , Figure 3 and Figure 4 In conjunction with the above embodiments, in this application embodiment, both the first extension 12 and the second extension 22 have a groove 30 disposed toward the frame beam 90, at least a portion of the frame beam 90 passes through the groove 30 and is connected to the inner wall of the groove 30.

[0052] It is understood that grooves 30 are provided on both the first extension 12 and the second extension 22, and the extending direction of the grooves 30 is the same as the extending direction of the frame beam 90 (both extend along the third direction Z). This arrangement allows a portion of the frame beam 90 to pass through the grooves 30 (e.g., when the first extension 12 and the second extension 22 are located at the bottom of the frame beam 90, a portion of the bottom of the frame beam 90 can pass through the grooves 30), thereby reducing the overall height of the first frame 10 and the second frame 20. During vehicle operation, this structural arrangement increases the distance between the first frame 10 and the second frame 20 and the bottom surface, which in turn increases the distance between the battery pack mounted on them and the ground, reducing the risk of the first frame 10 and the second frame 20 colliding with foreign objects on the ground during vehicle operation, and improving the safety of the battery pack to a certain extent.

[0053] Please see Figure 3 , Figure 4 and Figure 5 In conjunction with the above embodiments, in this embodiment of the application, the battery pack frame includes a connector 40. At least a portion of the first extension 12 and at least a portion of the second extension 22 are both located on one side of the connector 40 in the second direction Y, and both are connected to the connector 40.

[0054] It is understandable that the first extension 12 and the second extension 22 can be connected by a connector. The first extension 12 and the second extension 22 are generally arranged opposite each other (in order to avoid the battery pack installed on the frame beam 90, the first extension 12 and the second extension 22 are generally arranged on both sides of the battery pack. If the corresponding first extension 12 and the second extension 22 are staggered vertically or horizontally in this case, the overall size of the first frame 10 will be increased in the second direction Y or the third direction Z, or the overall size of the second frame 20 will be increased in the second direction Y or the third direction Z, which is not conducive to the use of space). Therefore, the connector 40 is used to overlap the first extension 12 and the second extension 22 respectively, so that at least a part of the first extension 12 is located on one side of the connector 40 in the second direction Y, and this part is fixedly connected to the connector 40; at the same time, at least a part of the second extension 22 is also located on one side of the connector 40 in the second direction Y, and this part is also fixedly connected to the connector 40. The first extension 12 and the second extension 22, which were originally positioned opposite each other, only made contact at their ends, and the connection area between them was small. Now, the two are connected by the connector 40, and the connection area between the two and the connector 40 is large, which can improve the stability of the connection, and thus improve the stability of the connection between the first extension 12 and the second extension 22.

[0055] Please see Figure 3 and Figure 4 In conjunction with the above embodiments, in this embodiment of the application, at least a portion of the frame beam 90 is located between the connector 40 and the first extension 12, and is connected to the first extension 12 and the connector 40 respectively. At least a portion of the frame beam 90 is located between the connector 40 and the second extension 22, and is connected to the second extension 22 and the connector 40 respectively.

[0056] Understandably, at least a portion of the frame beam 90 is connected to the connector 40. At least a portion of the frame beam 90 is disposed between the connector 40 and the first extension 12, and at least a portion is disposed between the connector 40 and the second extension 22, allowing the frame beam 90 to support the connector 40 and improve the stability of the connector 40 installation. Preferably, both ends of the connector 40 can overlap corresponding parts of the frame beam 90, and the two ends of the connector 40 are connected to the corresponding parts of the frame beam 90 respectively by bolts or other fixing structures. Furthermore, since at least a portion of the connector 40, the frame beam 90, and the first extension 12 are arranged sequentially along the second direction Y, they can be connected simultaneously by bolts or other fixing structures. Similarly, since at least a portion of the connector 40, the frame beam 90, and the second extension 22 are arranged sequentially along the second direction Y, they can be connected simultaneously by bolts or other fixing structures. This arrangement can improve the stability and firmness of the connector 40 installation, which further improves the stability of the connection between the first extension 12 and the second extension 22, ensuring that the first frame 10 and the second frame 20 will not easily shake.

[0057] Please see Figure 3 , Figure 4 and Figure 6 In conjunction with the above embodiments, in this embodiment of the application, the battery pack frame includes a plurality of flat plate members 50. The plurality of flat plate members 50 are located on one side of the connector 40 in the third direction Z and are connected to the connector 40. At least one flat plate member 50 is disposed on the side of the frame beam 90 opposite to the first extension 12, and at least one flat plate member 50 is disposed on the side of the frame beam 90 opposite to the second extension 22. The third direction Z intersects with the first direction X and the second direction Y. Preferably, the third direction Z is perpendicular to the first direction X and the second direction Y.

[0058] Understandably, at least one flat plate 50 is disposed on the side of the frame beam 90 away from the first extension 12 and connected to the connector 40. That is, the flat plate 50 is disposed at the connection point between one end of the connector 40 and the frame beam 90. Since the connector 40 and the frame beam 90 are typically connected by bolts at this location, significant stress occurs when tightening the bolts. By disposing of at least one flat plate 50 at this location on the connector 40, the large surface of the flat plate 50 abuts against the frame beam 90, increasing the stress-bearing area (through the contact between the large surface of the flat plate 50 and the frame beam 90, a portion of the force on the connector 40 is transferred to the frame beam 90 via the flat plate 50), reducing the stress at the connection point between the connector 40 and the frame beam 90, and preventing damage due to excessive or concentrated stress at the connection. Similarly, at the other end of the connector 40, that is, on the side of the frame beam 90 away from the second extension 22, at least one flat plate 50 can be provided, which is connected to the other end of the connector 40. Since the other end of the connector 40 may also be connected to the frame beam 90 by bolts, the function of the flat plate 50 is to reduce the stress at the connection and prevent damage to the connection due to excessive or concentrated stress.

[0059] Please see Figure 6 In conjunction with the above embodiments, in this embodiment of the application, the connector 40 includes a first part 41, a second part 42, and a reinforcing part 43.

[0060] At least a portion of the first extension 12 and at least a portion of the second extension 22 are both located on one side of the first part 41 in the second direction Y, and both are connected to the first part 41. The second part 42 is located on the side of the first part 41 away from the first extension 12 or the second extension 22, and is connected to the first part 41. The extension direction of the second part 42 intersects with that of the first part 41. Preferably, the extension directions of the second part 42 and the first part 41 are perpendicular to each other. The reinforcing part 43 is located on the side of the first part 41 away from the first extension 12 or the second extension 22. The reinforcing part 43 is connected to the first part 41 on one side in the second direction Y, and is connected to the second part 42 on one side in the third direction Z.

[0061] Understandably, a portion of the first part 41 on the connector 40 can be connected to the first extension 12, and another portion can be connected to the second extension 22, thereby connecting the first extension 12 and the second extension 22 into a whole, improving stability. A second part 42 can be connected to the side of the first part 41 opposite to the first extension 12 or the second extension 22, with the extension direction of the second part 42 perpendicular to the extension direction of the first part 41. To ensure the stability of the connection between the first part 41 and the second part 42, and to improve the overall stability of the connector 40, a reinforcing part 43 can be connected to both the first part 41 and the second part 42. The reinforcing part 43 is located on the side of the first part 41 opposite to the first extension 12 or the second extension 22, and has a right-angled triangular structure. Its two right-angled sides are connected to the mutually perpendicular first part 41 and second part 42, thereby improving the stability of the connection between the first part 41 and the second part 42, thus increasing the overall strength of the connector 40 and preventing it from easily deforming. Among them, the first part 41, the second part 42 and the reinforcing part 43 can all be metal structures with high strength.

[0062] Please see Figure 7 and Figure 8 In conjunction with the above embodiments, in this embodiment of the application, the battery pack frame includes multiple fasteners 60. The two sides of each fastener 60 in the first direction X are planar structures. A fastener 60 is provided between each first body 11 and the frame beam 90, with the first body 11 connected to the frame beam 90 via a corresponding fastener 60. Similarly, a fastener 60 is provided between each second body 21 and the frame beam 90, with the second body 21 connected to the frame beam 90 via a corresponding fastener 60.

[0063] It is understandable that the frame beam 90 may have other structures on both sides in the first direction X, making the two sides of the frame beam 90 not flat, which is not conducive to the installation of the first frame 10 and the second frame 20. By setting a fastener 60 (the fastener 60 can be a flat structure) between the first body 11 and the frame beam 90, since the two sides of the fastener 60 in the first direction X are both flat, the fastener 60 can be first installed on the side of the frame beam 90, so that one side of the fastener 60 in the first direction X is connected to the frame beam 90. Then, the first body 11 or the second body 21 is installed on the corresponding fastener 60, so that the other side of the fastener 60 in the first direction X is connected to the first body 11 or the second body 21. This can improve the flatness of the installation of the first body 11 or the second body 21, so that the two are installed in a relatively neat state and avoid tilting relative to the frame beam 90.

[0064] Please see Figure 9In conjunction with the above embodiments, in this embodiment of the application, both the first frame 10 and the second frame 20 have a receiving cavity 70 for accommodating a battery pack; the battery pack frame includes a plurality of mounting members 80. Both the first frame 10 and the second frame 20 are provided with a plurality of mounting members 80, which are arranged at circumferential intervals along the opening of the receiving cavity 70 for mounting the battery pack.

[0065] Understandably, both the first frame 10 and the second frame 20 are provided with receiving cavities 70 for accommodating the battery pack. The openings of the receiving cavities 70 are generally oriented downwards (if the openings were oriented upwards, the upper parts of the first frame 10 and frame 20 would be other structures of the vehicle chassis, obstructing the installation of the battery pack and preventing it from being installed into the receiving cavity 70), thus facilitating battery pack installation. Multiple mounting components 80 are provided at the bottom of both the first frame 10 and the second frame 20. These mounting components 80 can be arranged circumferentially along the openings of the receiving cavities 70. After the battery pack is installed into the corresponding receiving cavity 70, the mounting structure on the battery pack can be connected to the corresponding first frame 10 or second frame 20 via the mounting components 80, completing the battery pack installation. The mounting components 80 can be threaded sleeves, connected to the bottom of the first frame 10 and the second frame 20 by welding. The outer periphery of the battery pack is generally provided with a skirt structure, which is fixedly connected to the first frame 10 or the second frame 20 via multiple threaded sleeves and bolts.

[0066] Please see Figure 1 and Figure 10 This application embodiment also includes a vehicle comprising a frame beam 90 and the aforementioned battery pack frame. The frame beam 90 has a load-bearing space 91 for supporting the battery pack. It is understood that the frame beam 90 generally has multiple crossbeams and longitudinal beams, with the crossbeams extending along a first direction X and the longitudinal beams extending along a third direction Z. The load-bearing space 91 can be formed between the crossbeams and longitudinal beams. Besides installing the battery pack within the battery pack frame, this load-bearing space 91 can also be used to support the battery pack, installing at least a portion of it inside, and then connecting the battery pack to the frame beam 90 using bolts or other fixing structures. This configuration can accommodate more battery packs, improving the vehicle's range.

[0067] Please see Figure 1 and Figure 10 In conjunction with the above embodiments, in this embodiment of the application, the frame beam 90 includes two support parts 92 and two fixing parts 93.

[0068] Two support portions 92 are arranged at intervals along a first direction X. A first frame 10 or a second frame 20 of the battery pack frame is provided on the opposite side of the two support portions 92. Each support portion 92 has a first flange 921 and a second flange 922 on both sides in a second direction Y. The first flange 921 and the second flange 922 extend toward the adjacent support portion 92. A fixing portion 93 is located inside the support portion 92 and is connected to the side of the corresponding first flange 921 facing the second flange 922. The fixing portion 93 extends along a third direction Z.

[0069] Understandably, the two support sections 92 on the frame beam 90 are longitudinal beam structures. The first frame 10 and the second frame 20 are respectively located on the outer side of the corresponding support section 92. Each support section 92 is provided with a first flange 921 and a second flange 922. The first flange 921 and the second flange 922 can be formed by bending the upper and lower parts of the support section 92, and both the first flange 921 and the second flange 922 extend towards the other support section 92 (or extend away from the direction of the corresponding frame structure). Among them, the first flange 921 is located at the bottom of the support section 92, and the second flange 922 is located at the top of the support section 92. The fixing part 93 is located on the side of the first flange 921 facing the second flange 922 (the fixing part 93 can be a long plate or a long strip structure). It can be fixedly connected to the first flange 921 by bolt structure, or the fixing part 93, the first flange 921 and the corresponding battery pack structure can be connected together by bolt structure. Since the fixing part 93 extends along the third direction Z, it has a large contact area with the first flange 921. On the one hand, it can improve the structural strength of the first flange 921. On the other hand, it can evenly transfer the load-bearing force on the fixing part 93 or the bolt structure to the first flange 921, avoiding excessive stress concentration that could cause deformation or damage to the first flange 921.
